[PATCH 4.9 21/30] btrfs: fix type of parameter generation in btrfs_get_dentry

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

From: David Sterba <dsterba@suse.com>

commit 2398091f9c2c8e0040f4f9928666787a3e8108a7 upstream.

The type of parameter generation has been u32 since the beginning,
however all callers pass a u64 generation, so unify the types to prevent
potential loss.
